Fight between close friends at party turns deadly on Sydney street

Police are hunting for an "armed and dangerous" 21-year-old after a disagreement at a party on Saturday night turned deadly the next day.

Joshua George was shot dead on a Sydney street in broad daylight on Sunday after having a fight with a close friend, Graeme Smith, at the party in the city’s south west the previous night.

The pair had arranged to meet on Sunday afternoon to sort it out. Mr George brought two friends - a male and female - along as "moral support", yet just seconds later, he was lying dead on Gidley Crescent, Claymore, with a single gunshot wound to his chest.

It is not clear what sparked the fight on Saturday night but police believe Mr George, 24, and his alleged killer, Mr Smith, 21, barely spoke a word when they met just after lunch on Sunday.

Police spoke to Mr George's two shaken friends immediately after, but they then "disappeared" and detectives are trying to get in touch with them again. They are also appealing for anyone who witnessed the argument at the party to come forward.

There was no discussion, just 'bang'. Witnesses have told us that everything happened that quickly, there was not much time for banter

Inspector Brett said both Mr Smith and Mr George were known to police.

Friends of Mr George's described him as a devoted father to his young daughter, Madison, and a big hearted man who was well known around Campbelltown.

"There's not a person in [Campbelltown] that hasn't had a good time with u brother, always stood strong and had our backs, ur in a better place now joshy G this world is putrid and ugly," posted another.

Brittany Phillips said she had spent time with Mr George in the days before his death and was "mucking around with you, hitting you with a pillow".

"You can be a pain but deep down you had a heart. You're the funniest guy," she posted.
